Peer to peer
Communication between users
§ Peer to peer successful
– 60-80% of internet traffic is peer to peer
– Bit Torrent alone 30% of internet traffic
– Skype over 3 million users on line
§ And cheap
– Use CPU, Disk, Bandwidth of peers
§ Resilience come from mass of nodes
– Logic and data spread over all nodes
– Resembles many biological systems
Will Peer to peer also dominate mobile world?

Summary
§ Mobile application revolution just starting
§ Client - Choices
There are basically three choices available:
– Fat (or thick) application implemented in phone
– Thin web browser
– Peer: distributed applications across nodes
§ None of the choices are inherently bad or good,
?
– Each own strengths and weaknesses.
– Successful client experiency depends on criteria.
§ Who will develop Key applications for the mobile century
– What are they
– What will be the business
